Justin Sullivan/Getty Images(CHICAGO) -- The first order of business college graduates should conduct is going through their social media sites for anything that looks the least bit incriminating.

According to the Chicago-based consulting firm Challenger, Gray & Christmas, six out of 10 hiring executives say they now check a job applicant's social activity, either all the time or some of the time.

In a survey of 100 hiring executives conducted last month, CEO John Challenger says of those who investigate social media activity, six percent admit it has a significant impact on their decision to put a candidate on their payroll.

Meanwhile, 40 percent of social media checkers admit what an applicant has on their site will play some role in their decision to hire them.

Challenger says the bottom line is that "When it comes down to a handful of qualified candidates, hiring managers will tend to gravitate toward those that did not raise any red flags."

LinkedIn profiles notwithstanding, it's what's posted on Facebook profiles that tend to get young job seekers in trouble.

Appropriately, the survey is titled, "Will Social Media History Trip Up College Graduates?"
